Hi Kerry,
Congrats on getting your little buttons this weekend...I had 10 out of 12 hatch in the incubator last week and they are doing great, growing fast, so sweet!! I have successfully kept and still keep buttons in my parakeet aviary....although there are ony two pararkeets in there right now, there has never been any problems (in my experience anyways). Check out this website, there is very useful info that will help you care for your little guys.
